Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539498, here are decompositions:

31 + 31539467 = 31539498
59 + 31539439 = 31539498
97 + 31539401 = 31539498
131 + 31539367 = 31539498
149 + 31539349 = 31539498
167 + 31539331 = 31539498
227 + 31539271 = 31539498
257 + 31539241 = 31539498

Showing the first eight; more decompositions exist.
